Patent DE-3315043-A1 (DE)
Title: Spray nozzle windscreen wiper blade for windscreen wash/wipe systems
Inventor: SCHORTEMEIER JULIUS
IPC: B60S1/52
Filed: 1983-04-26
Abstract: The spray nozzle windscreen wiper blade is provided for the sake of increased traffic safety by permitting satisfactory visibility in all light conditions and weather conditions. The blade achieves markedly better results by directly spraying water in front of the edge of the wiper blade through an internal water guidance system with spray nozzles. The technical advantages over a relatively long period of use with improved functioning of the entire windscreen wash/wipe system are supplemented by favourable economic effects. The previous necessity to change a used windscreen wiper - windscreen wiper blade holder with windscreen wiper blade - is now simply limited to changing the spray nozzle windscreen wiper blade by means of a simple fitting operation. Improved working results, longer period of use and the possibility of retaining parts of the windscreen wiper which do not necessarily need to be changed leads to considerable financial savings for the user and for the manufacturer.

Title: Fuel cell battery with improved membrane cooling
Inventor: MCELROY JAMES FREDERICK
IPC: H01M8/04
Filed: 1983-06-18
Abstract: A fuel cell battery containing membranes is characterised by an improved current distribution for the reactants and an improved heat removal. Internally cooled bipolar units for determining the reagent flow separate the ion-exchanger membranes of adjacent cells from one another. The coolant flows through the interior of the separator in such a way that one side of it is cooled to a greater extent than the other. The colder side of the separator is in contact with the fuel side of a membrane, while the hotter side of the adjacent separator is in contact with the oxidising agent side. The resultant temperature difference across the membrane minimises the drying-out of the fuel side of the hydrated cell membranes. <IMAGE>

Title: Method of reducing the WOW and FLUTTER values in the sound reproduction of magnetic-tape recordings
Inventor: DINTER KONRAD
IPC: G11B20/22
Filed: 1983-08-30
Abstract: The invention relates to a method of reducing the WOW and FLUTTER values in the sound reproduction of magnetic-tape recordings which is characterised in that a frequency existing on the medium is used as a measure of WOW and FLUTTER caused by uneven mechanical movement of the tape, the said frequency being used directly or indirectly via phase-locked loops to activate a buffer memory for error-free reading of the sound signal into the memory. In this case, the video vertical frequency, the video horizontal frequency, the video or audio time-code frequency, the video colour subcarrier frequency or any frequency which has a clear phase and/or frequency relationship with the tape and is high enough to incorporate the phase and frequency modulation caused by WOW and FLUTTER (sidebands) is used. <IMAGE>

Patent DE-3341544-A1 (DE)
Title: Door-locking system
Inventor: PECH JUERGEN DIPL ING
IPC: E05C9/06
Filed: 1983-11-17
Abstract: Door-locking systems with central closure, such as are used in ships or other air-tight or moisture-tight appliances, in most cases have a handwheel which carries a spindle, the spindle, equipped with suitable articulation devices, being movable up and down, with the result that operations for opening and closing tumbler elements connected thereto are triggered. The considerable disadvantage of known door-locking systems of this type is that, in the respective opening and closing position, the actuating mechanism for this operation tends to jam, thus leading to moments of considerable danger, since such faulty mechanisms cannot be actuated quickly enough, if at all, when the need arises. The door-locking system according to the invention eliminates this disadvantage by equipping the spindle nut, on its side pointing towards the handwheel, with damping devices which prevent a wedging or jamming of the spindle nut with stop parts in its end position.

Title: Camera system for determining focus by means of an exchangeable taking lens
Inventor: TANIGUCHI NOBUYUKI
IPC: G02B7/28
Filed: 1984-02-01
Abstract: A camera system having an autofocus system comprises a camera housing (BD) and an exchangeable zoom lens (LZ). The exchangeable taking lens stores different data values, which are transmitted to the camera housing in order to improve the automatic focusing. Such information is necessary in order to convert the specific defocusing information into a movement of the source (MO) of the driving force, in order in this way to execute automatic focusing. The source of the driving force in the camera housing can be controlled as a function of the data value of the exchangeable taking lens, and as a function of the focus information acquired. The driving force is transmitted to the exchangeable taking lens. Moreover, if an unfavourable state is determined, the camera housing is capable of locking the focusing or focal display as a function of a data value of the exchangeable taking lens. <IMAGE>
